Title: Improvements relating to gyro-compasses
IPC: G01C19/38
Filed: 1920-02-23
Abstract: 139,474. Sperry Gyroscope Co., (Assignees of Tanner, H. L.). Nov. 8, 1917, [Convention date]. Gyroscopic compass.-In order to reduce static friction, the angularly-displaceable element is maintained in a state of vibration in its frame. Means are also provided for oscillating the bearings of the gyro-casing and for reciprocating the gyro-unit on its support. The frame 11 carrying the gyro element is secured to a stem 10 journaled within a gimbal-mounted frame 5, and carries bearings 12, 13 and a thrust-bearing 14 for a ring 22 within which the gyro-casing 18 is pendulously supported on bearings 20, 21. Within the frame 11 is an electro-magnet coil 16 on a stationary core 70<1> which exerts an upward pull on the core 17 attached to the gyro-element which is thus magnetically suspended. The means shown in Figs. 1 and 2 for oscillating the gyrounit around the vertical comprise an arm 26 secured to the frame 11 and operating a sliding contact 24 working between fixed contacts 28, 29 connected respectively to electro-magnets 31, 32 between which is an armature 33 carried by an arm 34 secured to the frame 11. Means for reciprocating the gyro-unit vertically comprise a switch 35, Figs. 1. and 3, of magnetic material pivoted at 36 and normally held closed on the contact 37 by a spring 38, but adapted, when the magnetic flux is sufficiently large, to be drawn against the magnetic element 39 to close a short circuit through coil 41 and reduce the current through the coil 16. A fluctuating magnetic field is thus obtained and the gyro-unit is therefore reciprocated. In order that the card 60 may not be reciprocated also, the stem 61 has vanes 62 entering slots 63 in the boss 64 of the card. Means similar to those shown in Fig. 2 may be provided to oscillate the bearings 20, 21, a phase difference of 180 degrees being introduced between the oscillation of the two bearings to avoid torque on the frame 18. In a modified form of magnetic suspension, the gyro unit carries a coil normally held within an air gap in the magnetic circuit of the coil 16. The Specification as open to inspection under Sect. 91 (3) (a) describes also resilient means to reduce the effects of pitching comprising a member 47, Fig. 7 (Cancelled), connected by springs 51, 52 to a projection 53 of the frame 5 and pivoted at 46 to a bracket 45 secured to the ring 2; the portion 56 of the member 47 is attached to the piston 55 of a dash-pot 48 pivoted to the bracket 45. Similar means are provided around the N-S gimbal axis, between the ring 2 and bowl 1 to reduce the effects of rolling, the member 47 and dash-pot 48 being in this case pivoted to the bowl. This subject-matter does not appear in the Specification as accepted.

Filed: 1955-02-24
Abstract: 765,271. Fluxing and coating metal strip. WHEELING STEEL CORPORATION. Feb. 24, 1955 [Feb. 24, 1954; Feb. 24, 1954], No. 5545/55. Class 82(2) A continuous steel strip is galvanized, aluminized or given a terne coating after coating the strip with a flux. The flux coating is applied to a strip 1 in a bath 3 containing the flux and the strip is passed upwardly round a guide roller 4, liquid flux being added at 6 in the crotch between the strip and the roller. Brushes 8 and rolls 7 spread the flux to form an even coating and the flux is dried on to the strip in a heated chamber 9 before it contacts the guides 10. It is then fed to a metal coating bath 12 and may be preheated at 11. The speed of the strip, temperature of preheat and position of the guides 13 are correlated so that the flux/coating metal reaction is completed before the strip contacts the first guide 13. The rolls may be rubber surfaced and have spiral grooves on their periphery. Specification 753,470 is referred to.

Filed: 1975-02-10
Abstract: 1461035 Automatic control systems DORNIER GmbH 10 Feb 1975 [14 March 1974] 5610/75 Heading G3R An aircraft (helicopter) 2 tethered by a single cable 6 is automatically or manually stabilized in respect of its attitude, translational movement, angular velocity (Yaw), the speed of its power unit and the tension in the tethering cable. The cable is connected beneath the centre of gravity of the aircraft and its tension is measured at 12. Roll and pitch are sensed by gyros and translational movement by gyro and accelerators, their signals operating respective servomotors controlling cyclical changes in the angle of the rotor blades (of a helicopter). Yaw is also sensed by a gyro, control being by pressure jets from the engine exhaust. Cable tension and rotor speed jointly control the overall angle of the rotor blades and the power output of the engine. Fig. 3 (not shown). All controls are by servomotors operated by "switches" controlled by unspecified "controllers". In an alternative arrangement Fig. 4 (not shown), the pitch, roll and translational control signals are combined in a network which includes integration of the accelerometer and gyro signals and includes compensation of the accelerometer for the gravity constant. Desired values and manual control signals are provided by the ground terminal and transmitted via the tethering cable.

Title: Improvements in Apparatus for the Rapid Tanning of Hides and Skins.
Inventor: GILARDINI FELICE
IPC: C14C3/30
Filed: 1918-04-05
Abstract: 114,631. Gilardini, F. April 6, 1917, [Convention date]. Treating hides and skins with liquids; impregnating-apparatus, vacuum or pressure. -Rapid tanning of skins &c. is effected by subjecting both sides of the skin to tanning liquid under pressure, or one side to the liquid under pressure and the other side to a vacuum. The process is carried out in a machine having a series of mating plates 2, 2<1>, the upper of which can be raised by suitable mechanism and lowered to grip the skin 11. The plates 2, 2<1> are furnished with a number of cells 5, 5', all of which may be supplied with liquid under pressure, or the upper or the lower set with liquid under pressure, and a vacuum induced in the other set. The shapes of the cells in the several plates in the series are such that they overlap one another to tan the whole skin, when the latter has been moved forward through all the plates in succession. Suitable shapes are shown in Fig. 4. The skin may be mounted in a frame for the purpose of passing it between, and alining it in, the series of plates. Valves are provided in the passages leading to the cells to prevent loss of liquid or of vacuum through cells across which the skin does not wholly extend. The valves shown in Fig. 6 each consists of a ball 20 which can engage a seat 21 at either side. Fig. 8 shows a valve comprising an upper ball 23 connected by a shank 24, which may be telescopic, to a ball 25. Where no skin lies across a cell, the balls fall to close the upper and lower cell inlets, but are hld up by the skin itself in the other cells to allow pressure to be applied to the upper side of the skin and a vacuum to the lower. The whole machine may be caused to oscillate or rotate. In a modification, the pairs of plates may be replaced by pairs of cylinders, cased with resilient material and having radial cells, means being provided for automatically bringing into operation only the two rows of cells next to one another.

Title: Improvements relating to drive chains
IPC: F16G13/04
Filed: 1929-02-22
Abstract: 307,018. Morse Chain Co., (Assignees of Morse, F. L.). March 1, 1928, [Convention date]. Driving-chains with separate joint pins.-In driving-chains provided with semicylindrical joint-pins the pin is caused to move transversely of the chain to allow of the necessary adjustments as the chain passes over the sprocketwheel, the transverse motion being arrested before the rotation of one link relative to the other is complete, the resultant motion being a rotation about an axis forward of the axis of the curved face of the pin. In the construction shown in Figs. 2 and 3 the round face of the pin 3 leads and the flat face bears on a face 4<1> of the leading link inclined at such an angle to the general direction of the link that when the two links are in a straight line the tension raises the pin to the upper part of the opening, but when the chain bends round the sprocket the pin is forced to the lower part of the opening. Figs. 8 and 9 show a wear-resisting bushing 6 disposed about the round surface of the pin 3<c>. The bushing 6 of the apertures in the links are so shaped that the transverse motion of the pin is secured by the camming action of the links on the bushing. A bushing may be placed between the flat face of the pin and the links, which bushiug may also be constructed to shift the pin and links relatively by its camming action with the link. A form with bushings on each side of the pintle is also described. The Specification as open to inspection under Sect. 91 (3) (a) describes a form in which the flat face of the pin leads. This subject-matter does not appear in the Specification as accepted.

Title: Process of electrolytically refining tin bullion
IPC: C25C1/14
Filed: 1923-02-28
Abstract: 220,012. Marks, E. C. R., (American Smelting & Refining Co.). Feb. 28, 1923. Tin, obtaining.-In depositing tin from impure tin anodes, there is employed an electrolyte containing an organic sulphonic acid in quantity sufficient to prevent the formation of basic salts of tin and to produce a smooth, dense, and adherent deposit. A suitable electrolyte contains 4 per cent tin, 5 per cent sulphuric acid, 2 per cent hydrofluosilicic acid and 2 per cent cresol sulphonic acid. Sulphuric acid must be present in excess of the sulphonic acid to ensure precipitation of lead and to prevent solution of lead by the hydrofluosilicic acid. Lead-lined vats may be used. With anodes made from certain ores, the hydrofluosilicic acid may be omitted, 10-15 per cent sulphonic acid and 2-4 per cent sulphuric acid being used; in this case it is desirable to add a small amount of glue or other hardening agent. Compounds produced by sulphonating benzol, phenol, toluol or naphalene may be employed instead of cresol sulphonic acid. A current density of 8 amps per sq. ft. of cathode surface may be used. A temperature of 95‹ F. is preferred, the voltage being 0.2 to 0.25, but temperatures up to 130‹ F. may be used. At 65‹ F. a voltage of 0.3 to 0.4 is required. The process may be contained until 75-80 per cent of the anode is dissolved. A certain amount of tin may be dissolved in the electrolyte as a stannous compound before commencing refining. The formation of stannic compounds is undesirable. The electrolyte may be circulated by pumps and heated by steam coils.
